Why overselling amount does not change after completing order in Hybris?

[Former Member]

When i complete an order, according to order entries, stock amounts of products have to update. Let me give an example. Assume we have a product called P-X like that.

P-X: available:3, overselling:12

Then i give an order containing P-X with the quantity 6. After completing order, Hybris update method (updateActualStockLevel) does not change the overselling amount and stock amounts for P-X is as following.

P-X: available:0 overselling:12

And after that, i can order for this product up to the amount 12 whenever i want, since overselling amount is 12 and it never changes although available amount is 0.

Does it means that you can sell a product up to a certain amount for an order or sth else?

Note: Yes, i wrote a custom update stock to update available and overselling but i am not sure i understood the overselling philosophy properly in Hybris.
